Application filed ,iui 13, 1912. Serial no. 709,235;

To all whom it may concern:

Be it known that I. J OHN GL N IE HOL- BOURNS, a subject ofthe King of the United Kingdom of Great Britaiii and Ireland, and

residing at 188 and 189 Fleet street, London, .England, have invented new and useful I'm provements in Typographical Composing- Machines, of which the following is a specification. I

This invention relates to typographical composing machines and imp-articular is an improvement upon the escapement mechanism described and illustrated in the specification of application for Letters Patent Serial N imber 445681, filed July 27th 1908.

In that specification there is described an arrangement comprising a seriesof so-called pushers one in operative engagement with each of the vscapement levers and each itselfoperated in one direction by a lever (since known as a striker) and in the other direction by a spring. The strikers of-that arrangement are themselves actuatedby.

bell-crank levers or tumblers which are entime before the seat of the "damage is reached. o

The object of the present invention is'to overcome the just-named ifi'iculty' by at taching. theaforesaid chee s orb'rackets to the back of the assembler guide'in such mam nor that they, together with theentire bank of strikers, can, as a whole, be readily detached therefrom and removed from-the ma;

chine without in any way disturbing the assembler guide.

, In the accompanying. drawings which are to. be taken as part of this specification and read therewith: Figure 1 is a right-hand side elevation partly in vertical section of part-of a machine provided with the present imgag'ed with'the escapement rods in the ordithe extreme right and left-hand ends of the relatively detachable bar and bracket hereinafter described; Fig. 3 is'a vertical section on the lineB-B of Fig. 2; Fig. 1 is a Fig. 5 is an elevation taken from the, rightlatter figure removed.

In one arrangement according to this invention, as shown in Figs. 1 and 2, the cheeks or brackets 1 are formedias a complete ennumeral 1, extending throughout the bank of strikers 2 and bell-crank levers 3. This frame 1 is provided with one or more dove in the example illustrated) extending throughout its length and adapted to be slid endwise on to the corresponding dovetail rib or ribs 5 of a bar or bracket 6 rigidly secured to the backof the assembler guide 7. I II I, I i

The frame 1 may be secured in normal position by any suitable device, thus, in the arrangement shown in Figs. 1, 2 and 3, the dovetail rib 5 is of less width than is the moreover tapered ina longitudinal direction the wider end being toward the lefthand side of the machine. The dovetail groove 4, throughout its length, ma be ducing width toward the left-hand side of the machine; in either'case the space intervening between the adjacent sides of the rib 5 and groove 4, receives a longitudinally tapered gib 8 the right-hand or thicker end of which-is provided with a device -for forcto the bar 6, or for drawing it slightly to;

from the bar 6 to allow the former and the vfrom the machine'as a single entity.

a screw 9 passing freely through an up of the said gib and engagingin a screw threaded hole in the adjacent 'end of, the dovethil rib 5, the said screw having a collar 11 fast thereon, at one side of the lug 10,

and adjustable at theothr side of thelug Patented July 15, 1913.

right-hand elevation showing alternative means for locking the parts in positiomand j ward the right so as to release the frame 1 devices mounted thereon, to be'withdrawn' standing lug 10 fast to the right-hand end provements'; Fig. 2 is a front elevation of hand side of Fig. 4;, but with a part of this tity' or frame hereinafter referred to by the tail or equivalent groovesfl (it has only one dovetail groove 4 which receives it, and it is either of uniform width, or of gradually reing the gib leftward for locking the frame 1 The device for adjusting the gib 8 may. i as shown in Figs. 1 and 2, take the form of I thepushers in the event of the other parts having become worn, there may be provided a set screw 14: threaded through a lug,15 fast to the bar 6, and having a lock nut 15 16 thereon; by adjusting this set 's'crew'in the lug 15, the terminal position to which the frame 1' can be moved in aleftward direction relatively to the bar dean be varied according to requirements, the gib' 2o 8 serving to lock the frame 1 in any of such positions. The usual means may be provided fo disengaging the cscapenientrods 17 from the bell-crank levers 3 before the bank of strikers is withdrawn from the machine and for reengaging these partsafter the bank of strikers has been replaced in the machine; thus, as shown in Fig. 1, the wellknown hand lever 18 may be provided for so the purpose, this serving to move backward and forward the plates 19 which guide the upper ends of the escapement rods.- A; spring catch 20 engaging with a lug 21 on the-adjacent end of the frame 1 serves to prevent accidental disengagement of the escapement rods 17 from the tumblers 3, and when this disengagement is desired to be effected, the said spring catch is lowered, given a partial turn to temporarily lock it ao 'iin itsvdepressed position by a bayonet joint 22'and the lever 18 is then depressed to move it'from the position in which it is shown in full lines in Fig. 1, to that in which it is shown in dotted. lines in that "#5 figure. F or reengaging the escapement rods 17 with the tumblers 3 the last-named oporation is carried out in the reverse manner.

Instead of securing the frame 1 in positionby a gib S as before described, this may be effected by a mutilated screw 23 such as thatrepresented in Figs 4c and 5, in which arrangement a partial rotation of the screw in one direction will sut ice to disengage it from the frame 1 to allow-the latter to be .55 withdrawn from the machine. and a partial the entire bank of strikers 2, may be in two or more shorter sections each which would be provided with its own dovetail groove or grooves for engaging with the. common dovetail rib or ribs on the bar 6,.

and ifdesired, instead of the arrangement of dovetail ribs and grooves previously described, the reverse of this arrangement may obtain, the rib or ribs being on the frame 1 and the groove or grooves in the'bar 6 as shown for example in Fig. 4.

In the arrangement illustrated, the know pi-chute would, unless provision were made to prevent it, obstruct the withdrawal and replacement of the frame 1 and for that reason must be capable of being moved out of the way of the said f time. For that purpose the pi-chute can be pivoted to the front guide plate 25 by means of a screw, 26

which, whentightened, serves to secure the said pi-chute in operative positlop as indi cated 1n dottcdhnes in Figs; 1 and 2, and
